In what circumstances will the Federal District Court order that two defendants be brought to stand trial at the same time for the same crime?

Finally, considerations of judicial economy weigh heavily in the government's favor here. While the fact that it is usually more efficient to try two defendants charged with the same crime together rather than separately does not always outweigh a defendant's interest in severance, see United States v. Finkelstein, 526 F.2d at 524, we must conclude that the public interest in conserving judicial resources is increased, and the defendant's interest lessened, where the defendant does not move to sever until after the government has rested its case and the trial is almost over, as happened here.
